Hello! I'm trying to learn Spanish, and although I can pronounce words with a rolled R, I've realized that I'm doing it in an odd way. Instead of lifting my tongue to the area behind my front teeth, I basically fold my tongue and lower it slightly, if that makes any sense. I think it's probably most similar to a German or French R, because even though there's an obvious trill sound that sounds like a rolled R, there's also a slight "ch" sound, like "ich bin."
So I have a couple of questions. First of all, is it obvious to native Spanish speakers when someone is basically faking the rolled R? The way I pronounce words with a rolled R doesn't really sound different to me from the correct pronunciation, but maybe that's just because I'm not a native speaker. Second of all, if it is important that I learn how to pronounce the rolled R in the same way native speakers do, what are some tips for learning how? Thank you!
